Repeated 502 Errors

Support Help
1

We’re noticing this error show up sporadically. We arent able to recreate it. It started occuring around 2-3 weeks ago.

tool_call_id: c11e3b1b7adee879

Axios Error: error code: ERR_BAD_RESPONSE, error message: Request failed with status code 502 response status: 502

The tool call was made 4:38 into the call, with this response being received at 4:45.

A tool call prior to this (different function, but same endpoint) ran at 3:56 into the call and got a successful response by 3:58.

call id for this specific example is call_44b6a8b1a14130b597fdb1b76cb.

Please guide.

Hi @hussain Checking with the team

alright, for some more information, the tool calls go to our vps. I understand it could be an issue over on that end as well. Primarily wanted to see if others are facing the same or similar problem

Hello @hussain The 502 was returned to Retell by your n8n endpoint handling the bookAppointment custom tool — Retell POSTed the request and surfaced the upstream 502 verbatim; so failure is in your infrastructure.
